2. Description of Related Art

People in modern times pay much attention to their health and to keep their bodies in good shape by taking exercises. Indoor exercises with exercising equipments are become popular because people do not have time to go outside to look for a suitable gym or athletic park for exercising.

Conventional exercising equipments mostly and individually have single function and occupy large space of the living space inside the house. Therefore, all manufacturers of exercising equipments are dedicated to develop new equipments with multiple functions. However, the multi-functional exercising equipments mostly have complex structure and easily malfunction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

An exerciser chair in accordance with the present invention comprises a main frame with a rail, a seat assembly slidably mounted on the rail of the main frame, a stop formed on the rail to limit sliding movement of the seat assembly. A front end of the main frame selectively combines with a bicycling device, footrest device or lifting device. The seat assembly has arms for gripping and further has a pivotal backrest to provide a back-extending movement. Thereby, the exerciser chair has various combinations and operational selections in use.

With reference to FIGS. 1 and 2, a preferred embodiment of the exerciser chair comprises a main frame 10 (as shown in FIG. 2) that has a front foot 11, a rail 18, a sleeving tube 12, a rear foot 13, a supporting rod 14 and a fastener 15. The rail 18 is a rectangular rod. The front foot 11 is perpendicularly attached to a front end of the rail 18 at a middle portion of the front foot 11. The rail 18 has a rear end extending backward with a gradually increased height. The sleeving tube 12 is attached under the rear end of the rail 18 and receives the rear supporting rod 14 underneath. Then, the rear foot 13 is attached to the rear supporting rod 14 at its middle portion to keep the exerciser chair raised. Positioning of the sleeving tube 12 and the rear supporting tube 14 is achieved by the fastener 15 transversally penetrating both elements 12, 14. Two stops 16 are formed at two opposite sides of a middle portion of the rail 18. An ear 17 is formed at a bottom of the middle portion of the rail 18 and has a hook 171 thereon.

A seat assembly 30 rotatably mounted on the rail 18 of the main frame 10 and comprising a seat 31 and sliding mount 32. The sliding mount 32 is attached under the seat 31 and is a rectangular collar correspondingly and slidably engaged the rail 18. The sliding mount 32 has a front and rear ends respectively having multiple wheels 321. By driving the wheels 321, the sliding mount 32 enables to smoothly slide along the rail 18. An ear 323 is formed at a bottom of the sliding mount 32 and has a hook 324 thereon. At least one resilient element 20, spring with end hooks for example, engages the hook 171, 324 on the ears 17, 323 of the rail 18 and the sliding mount 32 to provide a training resistance force and a restitution force to the seat assembly 30 (as shown in FIGS. 1 and 2). Moreover, a pivoting block 322 is formed at the bottom of the sliding mount 32 and extends toward the rear supporting rod 14.

A backrest assembly 40 mounted on the seat assembly 30 and comprises a backrest 41, two arms 43 and two supporting tubes 42. Each supporting tube 42 is L-shaped and attached to a backside of the backrest 41. The two supporting tubes 42 are pivotally and respectively attached to two sides of the pivoting block 322 on the sliding mount 32 so that the supporting tubes 42 with the backrest 41 can be adjusted to different inclined angles. A resilient element 44, such as a resilient rope, has one end attached to a middle section of each supporting tube 42 and another end attached to the sliding mount 32 to provide the backrest 41 with the training resistance force and the restitution force. Moreover, the backside of the backrest 41 has a soft pad 411 operationally clamped between the backrest 41 and the wheel 321 when the backrest 41 leans against the seat assembly 30.

A foot-mounting assembly is attached to the front end of the main frame 10 and selectively modified into a bicycling device, a footrest device or an extending device.

The bicycling device 50 is attached at the front end of the main frame 10 and comprises a connecting rod 51, a wheel assembly 55, two cranks 52, two pedals 53 and a resistance-adjusting element 54. The connecting rod 51 is secured on the front end of the main frame 10 and has a free end. The wheel assembly 55 is mounted on the free end of the connecting rod 51 and covered by a shell that contains the resistance-adjusting elements 54 inside to control the exercising levels of bicycling device. The two cranks 52 are oppositely connected to the wheel assembly 55 to drive the wheel assembly 55. The two pedals 51 are attached to two distal ends on the two cranks 52 respectively for resting user's feet. Moreover, the wheel assembly 55 further has knob 541 thereon to control the resistance-adjusting element 54. Particularly, the resistance-adjusting element is a belt (now shown) attached to a periphery of the wheel assembly and selectively strangling the wheel assembly by the knob to provide different resistance. Because the bicycling device is a well-known structure in exercising equipments, redundant descriptions about the wheel assembly 55 and the resistance-adjusting element 54 are obviated here.

With reference to FIG. 3, when the backrest assembly 40 operates to perform a back extension movement, the two supporting tubes 42 pivotally mounted on the pivoting block 322 allow the backrest 41 being pushed backward to an inclined position. The resilient elements 44 secured between the middle portions of the supporting tubes 42 and the sliding mount 32 provide the resistance force to stress the training. When the user stops to push the backrest assembly 40, the resilient elements 42 pull the backrest 41 back to an erecting position.

With reference to FIG. 4, the bicycling device 50 can be replaced by the footrest device 60 that comprises a connecting rod 61, a transversal rod 62, and two stationary pedals 63. The connecting rod 61 is secured at the front end of the main frame 10 and has a free end. The transversal rod 62 has two ends and a middle portion perpendicularly combined to the free end of the connecting rod 61. The two stationary pedals 63 are respectively attached to the two ends of the transversal rod 62 for resting the user's feet.

With reference to FIG. 5, the bicycling device 50 can be replaced by the extending device 70 that comprises a connecting rod 71, a T-shaped rod 72, and two resilient elements 73. The connecting rod 71 is secured at the front end of the main frame 10 and has a free end. The T-shaped rod 72 has a two arms and a stand perpendicularly jointing between the two arms, wherein the stand pivotally connects to the free end of the connecting rod 71. The two resilient elements 73 are respectively attached to two sides of the extending device 70. Each resilient 73 has one end attached to a corresponding side of the main frame 10 and another end attached to a corresponding side on the stand of the T-shaped rod 72. Thereby, the resilient elements 73 provide the training resistance force when the T-shaped rod 72 is pivotally pushed outward and also provide the restitution force when the T-shaped rod 72 is released.

With reference to FIG. 1, the sliding mount 32 on the seat assembly 30 is driven to slide along the rail 18. When the sliding mount 32 abuts the stop 16, sliding movement is limited by the stop 16 and the sliding mount 32 can not move further.

According to above description, the exerciser chair in the present invention has the following advantages:

1. The exerciser chair has various operational modes such as sliding, back-stretching, bicycling, foot-extending movements for exercise selection and can replace a lot of exercising equipments. Therefore, equipment cost is correspondingly reduced and indoor space is sufficiently saved.

2. The exerciser chair of the present invention has simple structure so that malfunction on elements is avoided. Moreover, the product price and maintain fee of the exerciser chair are low.

Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present invention of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts any be resorted to without departing from the spirit and scope of the invention.
